Review on 🐕 Enhance Your Free Spirit In-Ground Fence with an Add-A-Dog Collar: Additional Shock Collar with Tone/Vibrate and Shock for Extra Control and Convenience by Joe Clayton

We have tried several different brands of invisible dog collars and these are by far the best we have tried! They are easy to install and you can tell they are made from very high quality materials. Our dogs didn't run over the invisible fence line like they did with the previous two brands we tried. They are also very durable. The battery life is amazing! We've had it for almost 5 months now and tonight I plugged it in to charge for the first time! However, we turn them off every night, which probably helped extend battery life. I can't say enough good things about these collars, they are top notch! I really wanted to see how well they worked for a long time before coming here to write a review. I'm very, very impressed!
